I have a legacy dish 500 set up with legacy LNB's, and another legacy dish at 65 deg.  All switches are located outside, I do not know what they are.  I have 2 satellite cables running to my basement, where I then have the connections to my receivers.  I currently feed an 811 receiver in the living room, and a DishPlayer 7200 in the bedroom.  I also have an old model 5000 receiver in a office, that I would like to feed by splitting the signal before the DishPlayer.  I have tried a standard cable splitter, but this did not work.  Could somebody tell me what I need to split this signal?
